Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Increased Ag nanoparticles stability through cellulose nanofibrils coatings [PDF]

Memoirs of the Scientific Sections of the Romanian Academy, 2020
The study presents the possibility of covering Ag nanoparticles in solutuon with cellulose with cellulose nanofibrils (CNFs)and oxidized cellulose nanofibrils, termed TEMPO (TCNFs)in order to increase their dispersility and stability over time.

Demixing of colloid-polymer mixtures in poor solvents

, 2002
The influence of poor solvent quality on fluid demixing of a model mixture of colloids and nonadsorbing polymers is investigated using density functional theory.

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

FEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Epoxy-anhydride vitrimers: Reprocessability via facile transesterification

Next Materials
Vitrimers represent a fascinating class of polymeric materials that exhibit both thermoset and thermoplastic behavior. These materials can be reshaped like thermoplastics while maintaining the robust, crosslinked structure characteristic of thermosets ...

Thrombolytic proteins profiling: High‐throughput activity, selectivity, and resistance assays

FEBS Open Bio, EarlyView.
We present optimized biochemical protocols for evaluating thrombolytic proteins, enabling rapid and robust screening of enzymatic activity, inhibition resistance, and fibrin affinity, stimulation, and selectivity. The outcome translates to key clinical indicators such as biological half‐life and bleeding risk. These assays streamline the development of

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Development of Chitosan-Coated Electrospun Poly(3-hydroxybutyrate) Biohybrid Materials for Growth and Long-Term Storage of Bacillus subtilis

Polysaccharides
Numerous bacterial species can both suppress plant pathogens and promote plant growth. By combining these bacteria with stabilizing substances, we can develop biological products with an extended shelf life, contributing to sustainable agriculture ...

Pathogenic Neurofibromatosis type 1 gene variants in tumors of non‐NF1 patients and role of R1276

FEBS Open Bio, EarlyView.
Somatic variants of the neurofibromatosis type 1 (NF1) gene occur across neoplasms without clinical manifestation of the disease NF1. We identified emerging somatic pathogenic NF1 variants and hotspots, for example, at the arginine finger 1276. Those missense variants provide fundamental information about neurofibromin's role in cancer.

Ultraviolet and thermally stable polymer compositions [PDF]

, 1976
A new class of polymers is provided, namely, poly (diarylsiloxy) arylazines. These novel polymers have a basic chemical composition which has the property of stabilizing the optical and physical properties of the polymer against the degradative effect of
